The Handover That Went Wrong
On February 20, 2025, Hamas handed over what it said were the bodies of four Israeli hostages: Shiri Bibas, 32; her sons Ariel, 4, and Kfir, who had been nine months old when taken; and Oded Lifshitz, 83. The handover occurred at a stage in Khan Younis, southern Gaza, under the terms of the first phase of the ceasefire agreement that had halted fighting since January 19. Hamas militants displayed four coffins on the stage as upbeat music played. Behind them hung a panel depicting the faces of the Bibas family beneath a cartoon of Benjamin Netanyahu drawn to look like a vampire.
The bodies were transferred through the International Red Cross to Israeli officials, who immediately began forensic identification at the Israel Institute of Forensic Medicine. By the following morning, they had results. The bodies of Ariel and Kfir Bibas were positively confirmed. The body of Oded Lifshitz was positively confirmed. The fourth body — the one Hamas had identified as Shiri Bibas — was not her. “This is an anonymous, unidentified body,” the Israel Defense Forces stated. “No match was found for any other hostage.” Israeli Prime Minister Benjamin Netanyahu accused Hamas of “an unimaginably cynical act,” saying the group had “placed the body of a Gazan woman in the coffin.”
Hamas attributed the discrepancy to what it called “the possibility of an error or mix-up of bodies” resulting from relentless Israeli bombing of Gaza that had left many people dead across the area. Whether the substitution was deliberate or the result of chaos and decomposition in a protracted conflict zone is contested and unresolved. What is documented is that the forensic machinery of the Israeli state, working through the night, produced identifications that Hamas’s own accounting could not match.
On Friday, February 21, Hamas transferred a second body. By Saturday morning, the Israel Institute of Forensic Medicine had confirmed it: Shiri Bibas. “Last night, our Shiri was returned home,” the Bibas family said in a statement. “Following the identification process at the Institute of Forensic Medicine, we received this morning the news we had dreaded — our Shiri was murdered in captivity and has now returned home to her sons, husband, sister, and all her family for rest.” She had been in captivity for 505 days.
Who the Bibas Family Was
Shiri Bibas was born in Argentina and had grown up in Israel. She was 32 years old when she was taken. By the accounts of everyone who knew her, she was defined by warmth and energy — someone described by those who mourned her as full of light and laughter, and by her sister-in-law Ofri as a person whose terrified face in the kidnapping footage was not who she was. “She begged people to remember Shiri full of light and laughter — not just the photo of her terror-stricken face as she was being kidnapped,” Ofri said at the funeral.
Ariel Bibas was four years old when Hamas took him. Kfir was nine months old — the youngest of all the October 7 hostages. Both boys had distinctive red hair that became, along with their mother’s anguished expression in the kidnapping footage, a visual symbol of the hostage crisis that was plastered across city streets and commemorated on their birthdays throughout the 16 months of captivity. They were the two youngest hostages taken on October 7 and became among the most widely recognised, their small faces appearing on posters, memorial installations, and social media campaigns across Israel and internationally.
Yarden Bibas, Shiri’s husband and the boys’ father, had also been taken hostage from Kibbutz Nir Oz on October 7 — but separately from his wife and children. He was released alive on February 1, 2025, during an earlier phase of the ceasefire exchange. He received the news of the forensic identification of his sons and ultimately his wife after his release, having returned to a country that was simultaneously celebrating the ceasefire and mourning what it was returning.
October 7, 2023: Taken from Nir Oz
Kibbutz Nir Oz sits within two kilometres of the Gaza border. On the morning of October 7, 2023, it was among the communities most severely attacked in the Hamas-led assault: approximately a quarter of the kibbutz’s residents were either killed or taken hostage — the highest proportion of any single community in the attack. Among those taken were the entire Bibas family.
Footage captured during the abduction showed Shiri clutching Ariel and Kfir as she was taken through the kibbutz by Hamas militants. Her expression — fear, desperation, her arms wrapped around her children — became one of the defining images of the October 7 attack and of the 16 months of hostage crisis that followed. The footage was not staged or reconstructed. It was filmed by Hamas militants themselves as documentation of what they were doing.
Also taken from Nir Oz that morning was Oded Lifshitz, 83, a longtime peace activist who had spent decades driving Palestinian patients from Gaza to Israeli hospitals for medical treatment. His body was returned in the same February 20 handover as the Bibas children. His remains were positively identified by the Israel Institute of Forensic Medicine alongside those of Ariel and Kfir. He had been held for 501 days before his remains were returned.
Forensic Analysis: Identifying the Dead in a Warzone
The forensic challenge of identifying human remains returned from a protracted armed conflict is among the most technically demanding in modern forensic pathology. The Israel Institute of Forensic Medicine — Abarbanel Street, Tel Aviv — is the primary facility for all such identifications in Israel, and its work in the Gaza hostage context reflects both the technical sophistication of contemporary forensic science and the specific difficulties created by conditions of war, imprisonment, and prolonged captivity.
Standard forensic identification of remains involves a hierarchy of methods: DNA comparison against reference samples from known relatives (the gold standard), dental record comparison, fingerprint comparison, and physical examination of distinctive biological features. In the context of hostage remains returned after more than 16 months of captivity in a conflict zone, all of these methods face elevated challenges. Remains may be decomposed to varying degrees. They may have sustained perimortem or postmortem injuries that complicate physical examination. The chain of custody from the moment of death to the moment of transfer — through Hamas’s possession, through an active warzone, through multiple hands — cannot be independently verified.
The identification of the Bibas children as Ariel and Kfir was made on February 20, the day of the initial handover, indicating that the forensic comparison was completed within hours of receipt and produced a definitive match. The speed of that identification — relative to the complexity involved — reflects both the quality of the reference samples available (the Israeli forensic infrastructure had been preparing for hostage returns throughout the ceasefire negotiations) and the relative physical condition of the children’s remains.
The failure to identify the fourth body as Shiri Bibas — and the subsequent positive identification of that body as an anonymous, unidentified woman with no match to any known hostage — raises a forensic question that has not been publicly resolved: how did Hamas come to present that body as Shiri Bibas? Possible explanations range from deliberate substitution (Netanyahu’s accusation) to genuine error in a situation of mass death and decomposition (Hamas’s explanation) to a combination of both — a situation in which the actual remains of Shiri Bibas had been confused with other bodies in a chaotic storage environment, and the substitution was made under conditions of uncertainty rather than intentional deception. The forensic evidence that would distinguish between these explanations — the identification of the anonymous woman, her origin, and the circumstances of her death — has not been made public.
What the Forensic Evidence Says About How They Died
The Israeli Defense Forces’ statements on the cause of death of the Bibas family are among the most forensically significant — and, given the contested geopolitical context, among the most carefully parsed — elements of the case.
Regarding the children: the IDF stated that Ariel and Kfir “were both brutally murdered by terrorists while being held hostage in Gaza, no later than November, 2023” — meaning they died within approximately six weeks of their abduction. The IDF added a specific and damning forensic detail: “The terrorists did not shoot the two young boys — they killed them with their bare hands.” This statement, if accurate, reflects physical forensic findings from the autopsy — the absence of projectile wounds and the presence of injuries consistent with manual killing (strangulation, suffocation, or blunt force with hands). The IDF did not elaborate on the specific physical findings that supported this conclusion, consistent with not disclosing forensic details that would be relevant to future legal proceedings.
Regarding Shiri Bibas: the family’s statement, informed by the forensic identification, states that she “was murdered in captivity.” The specific cause and manner of her death have not been publicly disclosed. The family noted they had not received confirmation from the Israeli government on the specific circumstances that led to the deaths of Shiri and her children — an acknowledged gap that reflects the sensitivity of ongoing proceedings and the incomplete nature of the forensic accounting available from a conflict zone.
Hamas has consistently denied killing the Bibas family, maintaining that Shiri and the children died in an Israeli airstrike in November 2023. That claim is directly contradicted by the IDF’s forensic findings on the children — the absence of projectile wounds and the presence of injuries consistent with manual killing are not findings consistent with death by airstrike. Hamas has characterised the IDF’s statements as “nothing but pure lies.” The forensic evidence, rather than the competing narratives of the parties in conflict, is the only independent source of information about what happened to these three people in captivity.
The Wrong Body: What It Means and What It Does Not
The substitution — or error — of Shiri Bibas’s body with that of an unidentified Gazan woman had immediate and significant political consequences, threatening to destabilise the fragile ceasefire that had been in effect since January 19 and producing some of the sharpest Israeli criticism of Hamas since the ceasefire negotiations began.
It also produced a specific forensic record. The unidentified woman’s body — described by Israeli forensic authorities as anonymous, with no match to any known hostage or identified database entry — represents an ongoing forensic case. The woman has a family. She has an identity. She died under circumstances that placed her body in Hamas’s possession in circumstances where it was transferred alongside confirmed hostage remains. Her identification, and the circumstances of her death and of how her body came to be in the coffin labelled with Shiri Bibas’s name, are forensic questions that have not been answered.
For the ceasefire and the broader hostage framework, the incident had both destabilising and ultimately stabilising effects. Netanyahu described the wrong body as a point of leverage to extract additional concessions from Hamas on hostage returns. An Israeli official told reporters that Israel would use the fact that Hamas failed to return Shiri’s body as a negotiating point for additional releases. Hamas, pressed by the diplomatic fallout, produced Shiri’s actual remains within 24 hours. Whether that rapid response reflects genuine logistical error corrected under pressure, or a more calculated sequence of events, is not publicly established.
Criminal Psychology: The Use of Hostages as Strategic Instruments
The killing of hostages — particularly children — while in captivity, and the subsequent use of their remains as elements of a negotiated exchange, occupies a specific and disturbing category in the analysis of terrorist hostage-taking as a strategic instrument.
Hamas’s October 7 hostage-taking operation was the largest such operation in the organisation’s history and was conceived, from the available documentary evidence, as a multi-purpose strategic tool: to create leverage for the release of Palestinian prisoners held in Israel, to complicate Israeli military operations in Gaza by creating a hostage calculus, and to generate international pressure on Israel through the moral weight of civilian hostages, including children and elderly individuals. The operation involved the capture of at least 251 people.
The killing of child hostages — if the IDF forensic findings are accurate — represents a specific and documented category of hostage-taker behaviour: the elimination of hostages who have become a liability rather than an asset. A nine-month-old infant and a four-year-old child generate enormous international sympathy and moral pressure, but they are also logistically demanding to hold, medically vulnerable, and — should they die in captivity of natural causes or become gravely ill — potentially more damaging to the holding organisation than their release. The IDF’s finding that the boys were killed “no later than November 2023” — within six weeks of abduction — is consistent with a decision made early in the captivity period rather than a sustained effort at hostage management.
The staging of the February 20 handover — coffins on a stage, upbeat music, a banner depicting Netanyahu as a vampire — reflects the deliberate use of the return of the dead as a psychological and propaganda operation. Hamas was not simply complying with ceasefire terms. It was performing a ceremony designed to inflict additional psychological harm on Israeli society while claiming the moral posture of compliance. The choice of music, the imagery, the staging — each detail was calculated. The forensic reality of what was in those coffins was simultaneously concealed from and displayed to the watching world.
Law and Legal Implications: Killing Hostages Under International Law
The killing of hostages in armed conflict is a war crime under international humanitarian law. The Geneva Conventions — specifically the Third Convention (on prisoners of war) and the Fourth Convention (on civilian persons) — prohibit the killing of persons taken hostage and hold parties to a conflict responsible for the humane treatment of all persons in their custody. Additional Protocol I to the Geneva Conventions makes explicit that the taking of hostages is prohibited as a grave breach, and that the killing of a hostage constitutes a war crime.
The International Criminal Court has already issued arrest warrants for Hamas leaders in connection with the October 7 attack, including for murder and hostage-taking as crimes against humanity. The forensic evidence emerging from the Bibas case — and from the returns of other deceased hostages — will contribute to the evidentiary record that the ICC prosecutor is building. The specific findings that the Bibas children were killed with bare hands, and within six weeks of their abduction, are directly relevant to charges of murder in the context of hostage-taking and to the determination of command responsibility.
The question of whether individual Hamas operatives — those who held the Bibas family in specific locations, those who were present when the children were killed, those who directed or authorised the killings — can be identified and prosecuted is a forensic and investigative challenge that will extend well beyond the current proceedings. Israel has stated it is investigating the identities of those who abducted and held the Bibas family. The forensic evidence from the autopsies, combined with any intelligence regarding the specific location and circumstances of the captivity, forms the investigative basis for that pursuit.
Under Israeli domestic law, the killing of an Israeli citizen by a member of a terrorist organisation constitutes murder and terrorism offences. Israel has prosecuted captured Hamas operatives in its military courts for October 7-related killings. Whether any individuals specifically connected to the Bibas family’s captivity and deaths can be identified, captured, and prosecuted through either Israeli military courts or the ICC framework is an open question.
Global Context: The Forensics of Hostage Returns in Armed Conflict
The forensic identification of hostage remains returned from armed conflict zones is a specialised field that has developed substantially over the past three decades, driven primarily by the aftermath of conflicts in the former Yugoslavia, Rwanda, Argentina’s Dirty War, and more recently the Islamic State’s captivity and killings of foreign hostages in Syria and Iraq.
The key institutional lesson from those contexts — applicable directly to the Bibas case — is the critical importance of ante-mortem data collection. Forensic identification of returned remains depends on the availability of reference samples and records: DNA reference samples from family members, dental records, medical records documenting distinctive biological features, and photographs that allow forensic anthropological comparison. Israel’s Institute of Forensic Medicine had been collecting and organising this data for all 251 October 7 hostages since the earliest weeks of the crisis, creating the infrastructure that allowed the Bibas children and Oded Lifshitz to be identified within hours of their return.
The substitution of an unidentified body for Shiri Bibas — and the rapid identification that exposed the substitution — illustrates both the capability and the limits of that infrastructure. The forensic system worked exactly as designed: it confirmed three identifications and rejected a fourth. But it could not prevent Hamas from making the substitution in the first place, and it cannot, by itself, answer the question of what happened to the unidentified woman whose body was in the coffin.
The International Committee of the Red Cross, which served as the transfer mechanism for the hostage returns, operates under neutrality principles that preclude it from making public assessments of the circumstances of returned remains. Its role is to receive and transfer — the forensic determination is made by the receiving party’s authorities. The ICRC’s involvement provides a record of chain of custody from the point of transfer, which may be relevant to future legal proceedings regarding the circumstances of the remains’ condition at the time of handover.
Investigation: What Remains Unknown
The specific circumstances of the deaths of Shiri Bibas, Ariel Bibas, and Kfir Bibas — where they were held, who was responsible for their captivity, what occurred in the hours and days before their deaths, and whether the killings were ordered, sanctioned, or carried out without authorisation — have not been publicly established. The IDF’s forensic findings are stated conclusions, not publicly documented methodology, consistent with the protection of an ongoing investigation.
The identity of the anonymous woman whose body was returned in Shiri Bibas’s place has not been disclosed. Whether she was a Gaza resident killed in an Israeli airstrike, a person who died in other circumstances, or someone with a different connection to Hamas’s custody operations is not known publicly. Her family, wherever they are, has not been informed through any publicly reported channel that their relative’s remains were part of an international hostage return ceremony.
Hamas’s explanation — that the substitution resulted from “an error or mix-up of bodies” due to Israeli bombing — has not been independently verified or refuted. The forensic analysis that could establish whether the substitution was deliberate (the unidentified woman’s cause and manner of death, her proximity to any Hamas holding facility, the condition of her remains relative to what would be expected from her stated cause of death) has not been made public.
The fate of the remaining hostages in Gaza — 59 as of the time of the first ceasefire phase, with nearly half confirmed dead by Israel — and the specific circumstances of those deaths, will constitute a prolonged and complex forensic and legal accounting. For each family waiting for a return, the Bibas case is both a template and a warning: the system can identify the dead, but it cannot always deliver them intact, in the right order, or on the first attempt.
Orange Balloons on the Highway
On February 26, 2025, tens of thousands of Israelis lined the highways as three caskets were driven from central Israel to the cemetery near Kibbutz Nir Oz. People stood on the sides of the road as far as the eye could see, sobbing and embracing each other as the procession passed. They held flags. They held signs reading “forgive us.” They released orange balloons — for Ariel and Kfir’s red hair, the most recognisable feature of the two youngest hostages, the feature that had made their faces identifiable on every poster and memorial across the country for 16 months.
Shiri Bibas, Ariel Bibas, and Kfir Bibas were buried in a joint grave next to Shiri’s parents, who had also been killed in the October 7 attack. Yarden Bibas — released alive from Gaza on February 1, having survived captivity that killed his wife and sons — was there. His sister Ofri asked forgiveness on behalf of the Israeli government and military for how long it had taken to bring them home, and said that forgiveness could only mean something after failures were investigated and officials took responsibility.
The forensic record now establishes that three members of one family were killed in Hamas captivity. The children were killed with bare hands within six weeks of being taken. The mother was murdered at an unspecified point in the 16 months that followed. Their father was released alive and returned to a country that received him with grief and that is still, more than a year after October 7, trying to bring home everyone it lost.
The orange balloons rose above the highway and drifted toward the sky over southern Israel, over the fields that border Gaza, over the place where this family had lived before the morning everything changed. Kfir was nine months old when he was taken. He never learned to walk.
